Best Performance For Higher-Horsepower Vehicles

Flowmaster's Super 40 Series Delta Flow Mufflers were developed for street/strip use. Utilizing Delta Flow Technology, these fully MIG-welded mufflers give the best performance to higher horsepower vehicles. Each Super 40 Series Delta Flow muffler contains a black, oversize case, which keeps the resonance down while the deep outside tone is sure to turn heads!
